GSA Indianapolis 2018

Indianapolis 2018 GSA workshop
Applied Geochemical Reaction Modeling
Indianapolis, Indiana USA • 2-3 November 2018

Register nowPlease join us in Indianapolis, the capital city of the Hoosier State, as guests of the Department of Earth Sciences at IUPUI for two days of hands-on training in applied geochemical reaction modeling. Then, stay on for the Geological Society of America 2018 Annual Meeting.

What you will learn. Following a fully hands-on format, you will learn to construct, trace, and interpret models of reaction in multi-component geochemical systems. Specific topics covered include:

  • Fluid mixing
  • Multicomponent equilibrium
  • Buffering reactions
  • Reaction, mass transfer kinetics
  • Kd, Freundlich, Langmuir sorption
  • Surface complexation
  • Polythermal reaction and mixing
  • Electrochemistry
  • Microbial catalysis and growth
  • Case studies and examples
  • Effective graphical presentation
  • Creating animation and video

The Reactive Transport Workshop was absolutely fantastic! Five stars, would recommend to a friend!

– Kristina G., Syracuse University

I thought the workshop was fantastic! The pacing and examples were very good and the course gave me a lot of ideas on how I can better use GWB.

– Morgan Warren, Golder Associates

I loved the workshop! It was just the right combination of instruction plus hands‑on.

– Karen Kinsella, GZA GeoEnvironmental


The workshop will be presented by Brian Farrell, Melika Sharifi, and Jenny Druhan. Brian and Melika are Geochemists at Aqueous Solutions LLC, maker of The Geochemist's Workbench®.
